Answer:

y=6*x+101

Step-by-step explanation:

Slope intercept form is y=mx+n, where m is the slope and n is the intercept.

Substituing in that equation the two points we get two different expressions. Now we have to solve a 2x2 system of equations.

I decide to solve it through substraction (literally one expression minus the other). That way we cancel out the n and obtain the value of m.

Now that we have m we plug in the value of m in one of the expressions to obtain the value of n.

To express the final equation we just plug in the values of m and n in the expression y=mx+n!

Which of the following equations represents a line that is parallel to the line with the equation y = 2/3x +2
Andreyy89

Answer: C. 4x - 6y = 3

Step-by-step explanation:

We only need to find a line with the same slope.

We will put 4x - 6y = 3 in slope intercept

4x - 6y = 3

-6y = -4x + 3

y = 4/6 - 3/6

y = 2/3 - 1/2

There you have it, a line with the same slope, which means it's parallel.

determine the sample sieze erequired to estimate teh mean score on a standardizes test within 4 [pints of the trrue mean with 98
Andreas93 [3]

Answer: Minimum sample size = 110

Step-by-step explanation:

Formula to find minimum sample size :

n=(\dfrac{z\times s}{E})^2 , where z = critical z-value for confidence level, s= sample standard deviation , E = margin of error

Given: E= 4 , s= 18

Critical z-value for 98% confidence = 2.327

So,  n=(\dfrac{2.327\times18}{4})^2

=(\dfrac{41.886}{4})^2\\\\=(10.4715)^2=109.65231225\approx110

Minimum sample size = 110
